fix: update js script to ts

[nameless-mc]

Why

Migrate JavaScript script files (bin/cli.js, build scripts, etc.) to TypeScript to improve codebase consistency and type safety.

What

Migrate bin/cli.js to TypeScript

Unified to the plugin-uploader pattern (thin wrapper):

• plugin-packer: Reduced bin/cli.js to a 3-line wrapper, moved meow parsing to src/cli.ts
• create-plugin: Reduced bin/cli.js to a 3-line wrapper, created new src/cli.ts
• customize-uploader: Reduced bin/cli.js to a 3-line wrapper, created new src/cli.ts

Migrate other JS scripts

• plugin-manifest-validator: script/generate-dts.js → script/generate-dts.ts
  • Added with { type: "json" } for Node.js v24 compatibility
• plugin-packer: Removed from-manifest.js, using package.json exports field instead
• dts-gen: bin/npm-build.js → scripts/npm-build.ts
  • Using import.meta.url for ESM compatibility

How to test

Checklist

• Read CONTRIBUTING.md
• Updated documentation if it is required.
• Added tests if it is required.
• Passed pnpm lint and pnpm test on the root directory.

Pull request overview

This pull request migrates JavaScript script files to TypeScript to improve codebase consistency and type safety across multiple packages. The migration follows a "thin wrapper" pattern for CLI entry points and converts build scripts to TypeScript with modern Node.js features.

• Unified CLI entry points across plugin-packer, create-plugin, and customize-uploader to use 3-line wrapper pattern
• Migrated build scripts (generate-dts.js, npm-build.js) to TypeScript with Node.js ESM compatibility features
• Replaced wrapper file (from-manifest.js) with package.json exports field for cleaner module resolution
